I've searched the web and here.. Does anyone have any CAD files of the AR15? If I cant strip it out of the AR15 file, Picatinny rails would be nice too. If anyone has one for a 30rnd mag, that would be helpfull too.

My 3D tool is Google's SketchUp, so I need to be able to import it into that if it's not in their format.

The DWG files come out flat in Google SketchUp (*.skp extention is native).. Does anyone have them in *.3ds
I only managed to find a wireframe lower receiver that is actual 3d. Any one have an upper? the wirerfame was a *dwg file.
